SPECIFICATION forming part of Letters Patent No. 354,731, dated December21, 1886.

Application filed August 16, 1886.' Serial No. 210,964. (No model.)

.To all whom it may concern:

Be it known that we, LE GRAND M. NORTON, EDWIN NORTON, and JOHN G.HODGSON, citizens of the United States, residing in Chicago,

in the county of Cook and State of Illinois, have invented a new anduseful Improvement in Soldering-Machines, of which the following is aspecification. Y

'Our invention relates to improvements in y 1o machines forautomatically soldering the joints or seams of square, rectangular, orother cans having flat or irregular sides. The object of our inventionis to provide an automatic machine of a simple and durable I 5construction which will operate to roll a square, polygonal, orirregular shaped can in van inclined position through a bath of moltensolder, so that each seam or corner of the can may be several timesrepeatedly immersed in 2o the molten solder, and thus insure the perfectsoldering of the can. By continuously rolling the can through the solderbath no part of it is long subjected to the heat and action of themolten solder; and in this way a square can 2 5 may be soldered on thesame principle and with the same degree of perfection as a round can maybe by rolling its corner or end seam through a similar bath, asdescribed in the Patent No. 274,362, to Edwin Norton,of March 3o 20,1883.

To this end our invention consists, in connection witha bath of moltensolder and a flux bath, of a can-carrier provided with a series ofrotatable can-holders and a track upon 3 5 which said can -holders rollas the carrier moves forward,said track servingto roll the can so thatits end seams roll in the molten solder.

, It also consists in mountingthe can-holder on pivots, so that afterone end has been soldered 4o the can may be turned with its soldered enddown while the solder is setting or cooling. We. find that in solderingcans by rolling or otherwise immersing them in molten solder, byproviding means for immediately turning the soldered seam or end ofthecan down ward after the can leaves the. bath, and by keeping it in thisposition while cooling, so

that the solder on the joints will have no tendency to run off, thejoints will be soldered 5o much more uniformly and perfectly.

Our invention also consists, in connection with an endless carrier andpivoted or swinging can-holders mounted thereon, of a second. orduplicate solder bath, so that by turning the swinging can-holder endfor end on its pivot the opposite end of the can may be soldered. As thecan rolls forward along the gages of the solder bath, the can not beingcircular and turning on its corners, itis obvious that the center oraxis of the can will not 6o move in a straight line, but in a series ofshort curves or an undulating or wavy line, depending on V'the outwardcontour or shape of the can; and the invention also consists, inconnection with the solder bath and the carrier, v ofaverticallyreciprocating or sliding revolving can-holder and a cam orguide track for moving said canholder up and down as it revolves and iscarried forward 0n its carrier," so that its center or axis will move inthe path 7o which the rolling movement of the can causes said axis todescribe.

It also consists in a vertically-reciprocating and revolving can-holdercomposed of a pivoted or swinging ring having a second revolv-` ingcan-holder ring mounted to revolve within the former.

It also consists, inconnection with said piv`- otal and revolving rings,of vertical guideways or slots in the carrier, in which said pivotalring 8O is mounted, so that the can-holder may reciprocate up and down.

The. invention also consists in the novel devices and novel combinationsof devices herein shown and described, and more particularly pointed outinthe claims.

In the accompanying drawings, which form a part of this specication, andin which similar letters of reference indicate like parts, we have shownone form and that whichwe be- 9o lieve to be the best form of machinenow known to us for practicing it.

In said drawings, Figure l is a side eleva tion of. the machine.` Fig. 2is a plan view of the same. Fig. 3 is an enlarged cross-section 9 5 online 3 3 of` Fig. 2. Fig. 4 is -an enlarged detail elevation of oneofthe links of the carrier. Fig. 5 is a section on line 5 5 of Fig. 4.Figs. 6. and 7 are enlarged detailelevations, showing the cam-track uponwhich thecan- Ico holder rides, and also the track for turning theholderl and upon which the can-holder rolls. Fig. 8 shows a slightmodification.

In said drawings, Arepresents the frame of the machine, which may be ofany suitable conlstruction; B, the can-carrier or traveling device uponwhich the can-holders are mounted, and by which the cans, or the cornersthereof, are conveyed along the flux-ing-bath C, the bath of moltensolder D, and the cooling device E. n

The carrier B is preferably a link-chain car- 'rier, and is mounted uponsuitable wheels, B

B', journaled in the frame at each end, and it travels in suitableguideways or tracks, a a, on the frame. The links B are provided withfriction-rollers lor pins b b, which travel in the guide-grooves a a.The guideways a a serve to keep the carrier in position and stead y it,so that the cans will be presented in proper relation to the acid andsolder baths.

F is a swiveling or pivotal ring, having pivot-pinsff, which lit inslotsffin the vertical sides of the link-B, so that this ring may havean up-and-down reciprocating movement in these slots. Y

G is aring mounted in the ring F, and which carries the can.` This ringG is provided with a socket, g, for the can, conforming in shapethereto. The socket mayr consist of angleplates to fit against the sidecorners of the can, as indicated in the drawings.

To enable the ring G to revolve easily in the ring F, it is providedwith friction-rollers g', which are j ournaled upon stud-pinsg2, screwedor otherwise fixed into the end facesof the ring G. The ring `F isfurnished with annular shoulders f2 for the friction-rollers g to fit inand roll upon. The friction-rollers g', thus secured to the ring G,serve also to keep said ring in place within the ring F, as the sides orends of the friction-rollers fit against the shoulders f2. The can X inthe socket g may thus at the same time have a revolving. motion on itsown axis by means of the revolution of the ring G in the ring F, Yaturningor revolving 'motion endwise by means of the swiveling or turningof the ring F on its pivots in the link B, and also a bodily up-anddownmovement by means of the up-and-down reciprocation of the ring F in theslots f of the link B.

-H is a track provided with notches or re cesses h h at intervals,corresponding to the side faces or corners of the can, adapted toreceive and engage corresponding pins or projections h h on therevolving can-holder ring G, and whereby the can is given a rolling orrevolving motion as it iscarried forward ,byV

nished with a friction-roller, k. v

The solder bath DA is provided with a gage tand flux.

or track, D', for the ends or head of the can to -rest against, and alsoa gage or track, D, for the side or corner of the can to rest against.

which engages the projection or arm k on the l ring F, and serves toturn the can into a vertical position,`as indicated in Fig. 3, so thatthe end of the can which has just been soldered will be down whilecooling andthe soldered seam stand in a horizontal position.- This camextends around the end of the machine, and serves to hold the can inthis position while it travels around the end of the machine and whileit receives the jets'of air from the cooling pipes or nozzles E. The camM is but a continuation or elevated portion of the cam K. The can X isplaced in the machine in its holder at the space or point marked As itis carried along by the carrier B it is rolled in an inclined positionthrough the' flux bath C and the solder bath D, the corner 1.

or seam of the can as it rolls projecting into the molten flux andsolder.l As the carrier moves forward, the pins or proj ectionsh' on thecan-holder ring Gengage the notches or recesses h in the track H, thuscausing the canholder ring G to roll on said track. At the same time thearms or projections k, fitting in the cam K, serve to give thecan-holder a gradual up-,anddown movement corresponding to thatwhich'the center or axis of the can has, due to the revolution orturning of the can on its corners. The can in `this -way is given thesame movement as though it were rolled by hand on its corners along thestraight dat gages D Dz of the solder bath. The cam K is arranged in aplane in relation to the pins f. so as to carry the can in an inclinedposition through the solder and fiuxing baths, and thusproperly projectthe corner of the can into saidbaths. The slots f in the sides of thelinks B have this same inclination, so that as the can-holder ring G ismoved bodily up and down by the cam-track K, the can will be keptparallel with itself and always be presented at the same angle to thesoldering andV fiuxing baths.

' The flux and solder in the flux and solder vessels C D. are heated Yby gas-jets or other suitable heaters, L L, and the joint to be solderedis heated by contact with the hot solder If preferred, however, the canmay be heated by suitable flame-jets or other heaters arranged in thepath of the can as it is carried along by the carrier B, before itreaches the solder bath. After `the can leaves the solder bath the arnfkon the ring F engages the curved, inclined, or elevated portion M of thecam-track and swings the ring F into a horizontal position, (asindicated in Fig. 3, on the left-hand side thereof,) and while held inthis position by the cam the recently-soldered joint is carried over the4cooling jets or pipes E, by or through which cold air or other coolingfluid is projected against the joint, which is thereby rapidly' cooled.The cooling-jets should be located around the end of the machine. Whenthe can reaches the position marked w it is turned end for end, anattendant revolving the ring F half around on its pivots f. As the canthus turned is carried forward its other end is uxed, soldered, andcooled in the same manner by the duplicate devices on the opposite sideof the machine. When the can again reaches the position marked a: on thedrawings,'an attendant removes the soldered can and replaces it byanother.

rlhe carrier B may be furnished with any desired number ofrevolving,endfor-end-swiveling, and vertically reciprocatingcan-holders, and the solder and iiuxing baths may be made of any desiredlength.l We prefer, however, that the flux bath should belong enough topermit the cans to make about two complete revolutions in rollingthroughit, and that the solder bath should be long enough to permitthree or four complete revolutions ofthe cans.

By your present invention cans of almost any irregular shape may beautomatically soldered. The cam-track K, which. raises andlowers the canbodily as it moves forward, will be so curved or shaped as to cause thecenter or axis of the can to describe the line as it moves forward, dueto the rolling motion of the can corner or seam on the gages of thesolder bath. The ring F is furnished with two guide-arms, 7c lc, one oneach side of a central vertical line, so that both` pivots f f of thering F will be raised and lowered equally by the cam K. The ring F alsohas a second pair of guide-arms, k k, on its opposite side to ride inthe cam Kon the opposite side of the machine when the can and its holderare turned end for end on the pivots ff for the purpose of soldering theother end ofthe can. Y

rlhe canfsocket g in the can-holder ring G should fit the can snugly,and so that the friction of the can in the socket will hold it inposition and still permit the can to be readily slipped in and out.nished vwith springs or yielding cushions of rubber or cloth to bearagainst the side faces of the can. The socket g may also be constructedto tit the can somewhat loosely, in which case, however, some guide orsupport will be required to sustain the can after it leaves the solderbath, when it is swung into a vertical position. While rolling throughthe acid and solder baths the gages on such baths would support the canand keep it from Slipping out of its socket.

The socket may be fur- In Fig. 8 we have shown'a modification of thecamtrack K, in which it is made in two parts, onev adapted to bearagainst the lower pairzof guide-arms k k and the other against the upperpair, instead of a grooved cam, as shown' in Figs. 6 and 7. Theoperatlonof the cam, however, is the same in both cases.

We are aware that heretofore machines have been made for solderingsquare or rectangular cans, wherein first one corner or end'seam of thecan is carried in ahorizontal path or slid through a-solder bath, andthen the can turned a'quarter of a revolution and another corner slidthrough a second bath, and so on, and that also machines have been madein which first one corner of the can has been dipped in a solder bathand then another, the can being turned a quarter of a revolution whileit is raised out ofthe bath. We make no claim to any such machines.

We are also aware of and make no claim to the device shown and describedin the patent to4 Graves, N o. 242,631,0f June 7, 1-88l,wherein asquarecan is revolved as it is carried through or with its end seamprojecting-in a bath of solder by means of a revolving canholder mountedin a pivotal carrier, and having a round or-circular periphery, whichengages a stationary straight track or wire cable, and wherein thepivotal holder is provided with an arm engaging a stationary sinuouscam, by means of which the carrier is tilted at different inclinations,so as to raise the lower end of the can somewhat when its corneristurning into the bath, or wherein, in lieu of such tilting of thecarrier, the can-holder is provided with a yielding spring-socket, whichmoves up and down in the holder as the corner of the can turns down intothe solder, stationarystraight guiderails being provided for the'cornersof the can to strike against as it turns down, and thus cause the socketto yield' against the springs.

IOO

Inour invention the can rolls throughk the bath, and thus moves forwardat each complete revolution a distance equal to its periphery or to thesum of its four or more sides. In said -Graves device the revolving canis carried forward at each complete revolution a distance equal to thecircumference of its holder, which itself rolls on a stationary straighttrack or wire cable, and though the can revolves as it is carriedforward through the-bath it does not have or describe a rolling motionalong its surface.

In our invention, while the can is given a true rolling motion by meansof the revolving up-anddown bodily-reciprocating can-holder and itsprojections or pins'and the stationary at the same depth at its cornersand sides. In said Graves device the revolving can-holder has noup-anddown bodily -reciprocating movement, and it either has a pivotalmovement which changes its inclination to the solder bath or it isprovided with a springsocket, so that the can itself, by strikingagainst a guide-rail, may raise itselfup and down against the spring ofsaid socket, which striking of the can against the guardrail not onlytends to injure it, but also by the jarring to disturb the unset solderon the seams.

In our invention the revolving can-holder is provided with faces,projections, or pins h', correlative to the shape of the can, or one foreach of its corners,which engage a corresponding cam or track, on whichthe revolving part of said holder rolls, andthe revolving part of theholder is mounted inside an np-and-downV bodily-reciprocating outer,part which rides upon a sinuous track or cam.

In our invention the can is rolled continuously through the solder bath,the' can being-'bodily raised as its corner turns down into the bath, sothat the seam projects a like or nearly like distance into the bath ofsolder at all times as it rolls through it; and this feature of ourinvention (the bodily raising of y tended and adapted for solderingsquare cans, I

the revolving square can as the corners turn down into the solder, sothat the seam projects no deeper into the solder when the corner` isimmersed than when the straight edge of the can is immersed) isindependent of the forward bodily movement of the can on the carrier B,and might be practiced or embodied in a machine having vno carrier, orwherein the canholder is stationary so far as any longitudinak movementis concerned, as also obviously might that feature of our inventionrelating to turning the can into a vertical position while the canV iscooling and thesolder becoming set.

The machine shown in the drawings is inor cans whose horizontal sectionis square. As all the four sides of such 'a can are equal, the

recurring curves of the cam-track K are ofcourse all alike and equal toeach other. If, however, the can were of a rectangular or other shape,and its sides unequal or of different form from each other, vt-herecurring curves of the can would correspond to the shape of the can andbe different from each other. The cam-track K operates in a measure onthe principle of a former used in machines'for turning irregular bodies,as gun-stocks, lasts, &c.

Vhile the edges and corners of the can are guided and in a measure restupon the gages D D2 of thesolder bath, it should, however, be understoodthat littleif anyweight of the can is supported by these gages orguides, and

that no part of the weight of the can-holder ring G or ring F comes uponthe can, or rests upon these gagesor guides. rIhe cam-track K, the trackII, and the track a a, which guides the links B, in fact support thewhole weight, so that the can is subjected to no strain, jars,

be lobserved that in soldering pyramidal-v shaped cans, or cans largerat one end than the other, -in such case the tracks on opposite sides ofthe machine will not be alike, or of the same size in respect to thelength and height of the curves on the cam-track, or the distancebetweenthe notches on the notched track; and in soldering. pyramidal canshaving rounded corners and unequal sides-fsuch as ,cans now commonlyused for putting np canned beef or pressed corn-beef and other meats-theshape of the curves in the camtrack will be varied by the roundedcorners of the can, and also by its unequalsides. Whatever the shape ofthe can to be rolled on its corner along the gagesof the solder bath,the cam-track will be so shaped or curved in correspbndence therewith asto raise and lower the center or axis of the can as it rolls, and iscarried forward by the carrier in just the manner that said axis israised or lowered when the can is being actually rolled upon a levelplane. l
